Technical Information
Since more than 75 Jahren Eich Rollenlager has been a popular and renowned specialist for particular cylindricalbearing.
Eich types BR and ABC the so called flexible bush bearingsare a specific kind the rings of which are not made of solid steel, as usual, but of specific wound strip steel.
Advantages of Eich flexible bush bearings:
__Qualified for high operating temperatures
__Low contaminants susceptibility
__Allows the use of small diameters in strand guiding rollsdue to low design height
__Their modular system makes possible the adaption ofthethe components to our customers‘ requirements
This qualifies the flexible bush bearings especially forchallenging operating conditions.
The latest generation of flexible bush bearings has been
designed with a special roller cage assembly that is
enabled to better absorbe emerging torsion.
In addition, this new concept of roller cage assembly offers
a better allotment of the emerging forces. It affords the
reduction of the peak load while raising the load rating.
Depending from the reqirements, the bearing can be fixed
in place by hardened thrust rings. In CCP the flexible bush
bearings are normally designed as floating bearing.

Basic components ABC bearings
Flexible outer bush & Flexible inner bush
Solid roller cage
The flexible bushes made of wound strip steel are used particularly as innerand outer bushes/races. The mounting of them can be executed easily. Theyhave a less wall thickness than a solid bush.Flexible bushes fit on the shaft and/or in the bore due their defined pre-tension. Under temperature the bushes grow with their surroundingconstruction. It will not be necessary to grind the shafts or the bores.Flexible bushes must not be forced axially.
The solid roller cage assembly is providinghigher load capacities than the flexible rollercage assembly. For this reason, it is suitableespecially for high dynamic and static loads, first and foremost on only low shock loads. In conbination with the flexible bushes it isforming a bearing unit that has beendesigned for being applied in continuouscasting machines.

Difference to the standard roller cageassembly type RM
ABC roller cage
ABC roller cage assembly: one of its featuresis its motility of one cage ring due to thegroove and tongue joint, which is in contraryto the previous one.
Standard (RM)
Standard roller cage assembly: its pins areriveted to the cage rings.
Difference to the standard Roller Cage Assembly (RM)
Unlike the standard cage the rolling element in theABC-bearing is supported by the bar over its entirelength.

• Heat stabilized up to 350°C
• General operation envirenments are continuouscasting maschines.
• Particular resistivity against negative effects thatmay emerge by high temperature, high loads, lack of greasing, intruding media like as tinder, water, casting powder.
• Compared with the standard Flexible Bush Bearing,BR-type, the ABC Bearing is suited better to takeaxial trusts that may arise in the strand-guiding roll.
